Miley Cyrus has gone from an apple-cheeked preteen to a confident singer/actress with the whole world watching. As Cyrus celebrates her 20th birthday on Friday, November 23, we recount her transformation in 20 photos.
Seen here at 13 in May 2006, Miley Cyrus was the star of the Disney Channel's "Hannah Montana" series, playing a teen with a secret pop star alter-ego.
The role turned Cyrus into a singer as well as an actress. Here, she performs at a Radio Disney concert held in Anaheim, California, in July 2006.
The urge to perform must run in the family. Cyrus, of course, is the daughter of country star Billy Ray Cyrus.
Cyrus' fame spilled over from the Disney Channel into mainstream pop culture. Here, she arrives at MTV's "Total Request Live" in 2007.
Before she turned 15, the young star was selling out concert stops as "Hannah Montana" and as herself, which she did in the fall of 2007 with the "Best of Both Worlds" tour.
Cyrus is a frequent guest at the American Music Awards. Here, she arrives at the 2007 show just days before her 15th birthday.
In 2008, Cyrus starred in the 3-D concert film, "Hannah Montana & Miley Cyrus: Best of Both Worlds." Here, she and Ashley Tisdale embrace at the film's premiere after party.
At the 50th Grammy Awards in February 2008, Cyrus debuted a more severe look than fans had seen in the past. In April of that year, Cyrus came under fire for an infamously suggestive photo in Vanity Fair that implied she was topless.
Pushing her acting resume beyond "Hannah Montana," Cyrus teamed with John Travolta for the 2008 animated feature "Bolt." Here, the co-stars arrive at the film's Los Angeles premiere in November 2008.
Cyrus' 16th birthday coincided with the American Music Awards in 2008, and she celebrated with a cake and friends backstage.
Cyrus had a box office success with 2009's "Hannah Montana: The Movie." Here, she arrives at the film's Los Angeles premiere in April 2009.
Cyrus stirred up more controversy at the 2009 Teen Choice Awards when she hopped on top of an ice cream cart and danced around a pole while singing her hit single "Party in the USA."
At the Grammy Awards in 2010, Cyrus showed off a more adult look and a new hair color.
Cyrus began dating her "The Last Song" co-star Liam Hemsworth in 2009, and the two went on to have a closely chronicled relationship. Here, the couple embraces at an Academy Awards party in March 2010.
Cyrus stole the show with her costume when she took the stage at the Rock in Rio Madrid Festival in June 2010.
Cyrus turned 18 two days after attending the 2010 American Music Awards on November 21. Not long after she celebrated her big day, a video leaked of Cyrus taking a bong hit of salvia.
In December 2011, still dating boyfriend Liam Hemsworth, Cyrus made headlines when she walked the red carpet at the CNN Heroes event in Los Angeles. The singer/actress later had to refute gossip that she'd had a breast augmentation.
After plenty of rumors, it was confirmed in June 2012 that Cyrus and Hemsworth were engaged.
When Cyrus chopped off her hair and styled it as a bleached blonde pixie in August 2012, it was the haircut heard 'round the world.
